When we first got all our chickens they were quite calm but now every single time I go to the backyard they bolt to me and won't leave me alone thinking I've got food. If i do give them food they go crazy for it and gobble it up so quickly, They have food in the coop and under the tree which is always full with pellets and a bird mix. They have access to two waterers also. Is this normal? some other people with chickens have said that they are hungry and and are just using the pellets and bird mix as a minimum to survive. I have noticed the eggs have started to change by having lots of brown spots and some have the calcified chunks too and not to mention many slightly misshaped eggs. I read all these are a sign of poor nutrition. Anyone else got tho problem or know anything about it?
